How to work it out

  1. Difference: 42 − 10 = 32
  2. Divide by the starting value: 32 ÷ 10 = 3.2
  3. Multiply by 100: 320%
  4. Check: Work forwards from the start: 10 × (1 + 3.2) = 10 × 4.2 = 42.

In a spreadsheet: =(42-10)/10*100. Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.

What the result means

The new value is 4.2 times the old one: for every 100 at the start there are now 420. The value has more than doubled.

Prices: an item whose price rises from $10 to $42 has gone up by 320%.

Why the change back is different

A 320% rise followed by a 320% fall does not bring you back to 10: it gives -92.4. The second percentage is taken of 42, not of 10, so to undo this change you need 76.1905% instead.
